Regular Blaschke Para-Umbilical Hypersurfaces in the Conformal Space ${\mathbb Q}^n_s$

Abstract

In [2] we have classified the Blaschke quasi-umbilical submanifolds in the conformal space ${\mathbb Q}^n_s$. In this paper we shall classify the Blaschke para-umbilical hypersurfaces in the conformal space ${\mathbb Q}^n_s$. That may be also considered as the extension of the classification of the conformal isotropic submanifolds in the conformal space ${\mathbb Q}^n_s$.
